More than two years since I was here :-) I had a reason to use this code again, and in going through it I found a small bug. As it stands, the code produces output like this, for a particular database app I'm writing:

86
87
`---90
|   `---91
    |   `---92
        |   `---93
`---88
    `---89
94

If you change &getarticles( $NewIndent . $IndentString, $reply); to &getarticles( $IndentString . $NewIndent, $reply); it works OK:

87
`---90
|   `---91
|       `---92
|           `---93
`---88
    `---89
94

YMMV, I've had no time to test this thoroughly.
